Task 14 - Input problem with Python3

Hello to everyone from this fantastic site!

As the title says I have trouble getting the input from Test case.
The first thing I fetch is, of course, the first number:

n = int(input())

So far so good :P. But the problem comes later, the format of the lines is <sign> <integer>, so I tried to get them in several ways, but I had no success...

1. I tried unpacking the input directly, as they are separated with a blank space: for sign, value in input().split(' '): value = int(value) The exception here said it couldn't unpack because it expected two values but got one.

2. I tried to do the same in two steps: for line in input(): sign, value = line.split(' ') Same exception as the former, sure enough, they're the same.

3. I also tried fetching the parts as substrings: for line in input(): sign = line[0] value = int(line[2:]) I got ValueError: invalid literal for int() with base 10: ''

But if I tried the former way without looping, I mean taking just the first line (after the lonely number), I have success.

line = input()
sign = line[0]
value = line[2:]
print("{} {} ({})".format(sign, value, len(value))

It even works if I convert value into int, but when I loop It raises the same exception. I thought there was an error on one of the inputs to take, but it makes no sense because they're generated automatically, aren't they? And I even check its length, since there may be an invisible character I get which doesn't allow me to parse the string into an int.

What is the probleme here? I'm unable to grasp it...

Any help would be appreciated :)

I will try with this idea :)
